Support for Arduino Uno R4

james-yoo commented 1 year ago

Are there any plans to support a new Arduino UNO R4 (Renesas RA4M1 Arm® Cortex®-M4)?

Hello, there is no plan for integrating Arduino UNO R4, but it is easy to integrate new platforms in this repo, and community contributions are very welcomed.

hi @pablogs9 can you point me to any documentation for integrating new platforms? Thanks

Hello, there is no official documentation for making new ports, but you can see some PR that have integrated new platforms:

In general, you will need to:

Determine which compiler (version specific) uses Arduino for the target platform
If not available in the building docker, add it here and PR changes.
Update the library_generation.sh script to use the compiler to build the micro-ROS static library and put it in the correct folder
Update CI to test your changes

In general, this is not a trivial process, but handling it with care should be possible to do it.

IMPORTANT

It is very important to check if one of the already precompiled libraries actually works for the platform.

For example, R4 uses a Cortex-M4 and we already have a precompiled Cortex-M4 library: https://github.com/micro-ROS/micro_ros_arduino/tree/iron/src/cortex-m4

Have you check if adding it as supported plaftorm it works out of the box?

Hi! I have just checked this issue. I made a PR to get Arduino UNO R4 working over USB

micro-ROS / micro_ros_arduino
